Just yesterday I was talking to someone about recent reports that the most popular content on video streaming services is old, not new entertainment. This article from Screenrant lists 7 suggested reasons for this phenomenon. All of them may have validity, but I wonder if there might be one more – the fact that the older the show, the less woke it’s likely to be. The less likely it will be to try to stuff some fashionable new moral imperative down the viewer’s throat.

In my own case, I’ve been spending my evenings of late with Amazon Prime, working my way through the Perry Mason series (1957-1966). There’s some irony in this – next to Lawrence Welk, there was no show I hated more than Perry Mason when I was a kid. I found it dull – few fisticuffs or gunfights, and half the show was people blabbing in a courtroom. But my mother loved it. Today, there’s almost nothing on television I enjoy watching more than Perry Mason. I guess that means that – despite all appearances – I may have matured a little.

Something else that’s changed about me is that I’ve become a writer. Therefore, I watch for plot mechanisms. And I’ve noticed something – something that’s probably been obvious to more perceptive viewers for a long time.

I’ve figured out how to guess whodunnit in a lot of the episodes – not all of them, but many.

Watch for the superfluous character.

The thing to bear in mind is that – especially in television – especially in the old days – budgets were tight. The revision process in script development often involved finding ways to cut locations (if you can find a way to repeat shooting locations and sets you can save a lot of money) and cut characters (speaking actors are an expense. Make two characters into one whenever you can.)

So if you’re watching an episode of an old series like Perry Mason (or Murder She Wrote, or Columbo, etc.), and you notice a character who has lines (not a non-speaking extra) but seems to be there for no other reason than to make conversation, they’re not there by accident. If you can think of no other reason for the producers to pay them, they’re probably the murderer.

This goes double if the superfluous character is a familiar actor whom you’re used to seeing in bigger roles.

Written fiction is easier. You can deploy a cast of thousands at no additional cost.
